I have a poodle/chin mix male 6 months, bought him from a pet store at 4 months where he was crated 24/7. We keep dog door open 24/7 and he still poops (dry)inside and at times just inside door. This happens when we aren't home and at times at night, both about every other day. We have poo/pee pads down which he misses. He follows our other like dog whom does not pee or poo inside. I don't spank and rub nose into poo and send outside unless I catch him, I greet him excitedly when he does not poo but. Any suggestions getting very frustrated!
